gameboy advance emulator pokemon emerald

I have a flashcard from the brand DSTWO and I already managed to download an emulator from GitHub, the so called gbarunner2.

So I would like to play the Japanese version of Pokemon Emerald on my Nintendo DSi.

PS: I have HUGE respect for all the computer-file-geeks out there!! Thank you for taking the time to read through! I'd be glad if someone could answer

Is there a solution somewhere out there? Is there a possibility to download an other emulator that works as good as gbarunner2? If I open the emulator on my DSi, the icon of Game Boy Advance popps up and then the screen turns white. I downloaded the file from the same website and it looks exactly the same as the Fire Red file. With that, the Pokemon Fire Red Japanese version I downloaded works perfectly smooth and I'm very happy! Unfortunately - as the title of this thread already implies, I would like to play Pokemon Emerald as well. I unpacked the file for my specific flashcard.

Hello, I hope this is the right section to post this! Disclaimer: I am not good with computers and files so maybe you can explain it to me slowly
